Version

V4.22.3

Describe the bug

I have a problem with my existing Teams messaging extension in Teams V2. With the old teams everything runs perfectly.

I have a messaging extension using the Bot Framework. Actions are defined which can be triggered from message and command box. On my server I did override OnTeamsMessagingExtensionFetchTaskAsync and created a MessagingExtensionActionResponse with a URL that includes placeholders, like {groupId} and {channelId}.

The messaging extension works fine when I use the old teams client (web or windows app). But if I switch to Teams V2 the placeholders are only replaced with values when the messaging extension is triggered from the message. If it is triggered from commandbox the placeholders are not replaced.

Expected behavior

Placeholder should be replaced with values when the messaging extension is triggered from message AND commandbox

@anne376 Do you happen to have examples of the change? It does sound like Teams changed something, but it will make it easier to confer with them with examples.

Hi @tracyboehrer, yes I think something has changed in Teams.

The original URL looks like this with placeholders:
https://Server/MyApp/Documents?TeamsGroupId={groupId}&TeamName={teamName}&Culture={locale}&theme={theme}&TeamsChannelId={channelId}

If I start an action commmand from command box in Teams V2 only theme and culture palceholders are replaced:
https://Server/MyApp/Documents?TeamsGroupId={groupId}&TeamName={teamName}&Culture=en-us&theme=default&TeamsChannelId={channelId}

If I start from the message in Teams V2 all placeholders are replaced (I just changed the IDs a bit ;) ):
https://Server/MyApp/Documents?TeamsGroupId=aaaaaaaa-6666-4444-9ca9-9c210a6599da&TeamName=Projekt-Team&Culture=en-us&theme=default&TeamsChannelId=19%3A11268b3aa666666c9eac093592b43fb6%40thread.skype
